• Question 124:

  A customer is piloting an EMC Data Domain system.

  

  Based on the Data Domain statistics shown in the exhibit, which type of data is being backed up?

  A. New data
  B. DD Boost backups
  C. Redundant data
  D. Replicated data
  A. New data

• Question 125:

  Scenario

  A customer with a fully virtualized environment has four ESX 4.1 servers in a cluster with a SAN solution for storage. Each ESX server is hosting 40 virtual machines and all virtual machines have the same local disk configurations:

  Disk1 = 50 GB

  Disk2 = 100 GB

  Disk3 = 256 GB

  In addition, the environment includes a NAS filer. The average time to fully backup all virtual machines on one ESX server using EMC DD Boost is three hours.

  The customer is interested in implementing an EMC NetWorker solution with Data Domain as a backup device. The backup server, storage nodes, and proxies are SAN-attached.

  Refer to Scenario .

  When configuring VADP backups in EMC NetWorker to protect the ESX environment, what is the minimum number of virtual CPUs recommended for virtual proxy's using the `hotadd' transport mode?

  A. 2
  B. 3
  C. 4
  D. 6
  C. 4

• Question 126:

  A customer performs weekly full backups and daily incremental backups. A typical full backup is 5 TB. There is usually a 20% daily change rate in data. A full backup completes in 10 hours while an incremental backup completes in 4 hours. Based on best practices, what is the minimum Data Domain throughput required?

  A. 292 333 GB/hr
  B. 450 550 GB/hr
  C. 585 666 GB/hr
  D. 1170 1332 GB/hr
  C. 585 666 GB/hr

• Question 127:

  An EMC NetWorker customer is considering using an EMC Disk Library as a target as shown in the exhibit. Two storage nodes need to access the same pool of virtual tapes. In addition, the customer wants to load balance the usage of virtual tape drives across the available connections. Based on EMC best practices, which satisfies these requirements?

  

  A. Assign each host initiator port a different set of virtual tape drives from the same virtual library
  B. Configure each host initiator with a different virtual tape library, pointing to a common pool of virtual tapes
  C. Assign all virtual drives to all host initiator ports and use Power Path
  D. configure all virtual tape drives on all initiators and enable Active Engine Failover
  A. Assign each host initiator port a different set of virtual tape drives from the same virtual library

• Question 128:

  Scenario A customer with a fully virtualized environment has four ESX 4.1 servers in a cluster with a SAN solution for storage. Each ESX server is hosting 40 virtual machines and all virtual machines have the same local disk configurations: Disk1 = 50 GB

  Disk2 = 100 GB Disk3 = 256 GB In addition, the environment includes a NAS filer. The average time to fully backup all virtual machines on one ESX server using EMC DD Boost is three hours.

  The customer is interested in implementing an EMC NetWorker solution with Data Domain as a backup device. The backup server, storage nodes, and proxies are SAN-attached.

  Refer to Scenario .

  Using a VADP proxy, EMC NetWorker is backing up 12 virtual machines concurrently in SAN transport mode. What is the total recommended RAM needed on the proxy?

  A. 6 GB
  B. 8 GB
  C. 10 GB
  D. 12 GB
  A. 6 GB

• Question 129:

  A customer is considering implementing an EMC Disk Library with Active Engine Failover (AEF). Front-end ports 1, 3, and 4 from Engine A will be connected to the SAN. On Engine B, front-end ports 7, 8, and 11 will be connected to the SAN. To ensure proper AEF functionality, what is the total number of front-end ports from both engines that need to be connected to the SAN?

  A. 3
  B. 6
  C. 8
  D. 12
  B. 6

• Question 130:

  While running a three-month pilot using a Data Domain appliance, a customer produces the space utilization graph shown in the exhibit. What does the "saw tooth" line for the compression ratio represent?

  

  A. Expiration of data
  B. Sanitization of data
